I don&#39;t really remember the steps exactly, do you? <br>

<br></div>
You could use the « svn diff » command, or if it&#39;s not from SVN, then unpack another copy (make sure you don&#39;t overwrite) and then do a diff of the two Makefiles with a command similar to :<br>
<br>
  diff -u fux_kinect_orig/Makefile fux_kinect_tim/Makefile<br>
<br>
if the newer lines appear as «-» instead of «+», you have to change the order of filenames (I get it wrong 50 % of the time)<div><br>

That &#39;undefined symbol&#39; thing probably happened now only because I was trying with a new build of latest Gem, which doesn&#39;t seem to work itself here. I now replaced it back with my previous Gem.pd_linux, and it behaves like before: I try to create [fux_kinect], and pd hangs, without ever finishing creating the object, and without messages.<br>

<br></div>
You can use gdb like this :<br>
<br>
  gdb --args pdextended fux_kinect-help.pd<br>
<br>
and then use the «run» command to start pd, and press Ctrl+c to force it to quit when it&#39;s hung, then use the «where» command to see a backtrace. Then post the backtrace here.<div><br>
<br></div></blockquote></div><div>ok, only difference here is that doing ctrl+c didn&#39;t kill pd (just &#39;^CQuit&#39; in the gdb prompt. doing &#39;where&#39; anyway now gives:</div><div><br></div><div>#0  0xb7fe1424 in __kernel_vsyscall ()</div>

I could probably look up the Valgrind output, if it&#39;s relevant. gr, Tim<br>

<br></div>
For a hang, it&#39;s better to use GDB.<br>
<br>
GDB and Valgrind are largely complementary.<br>
<br>
There&#39;s also a GUI for Valgrind if it helps you. I don&#39;t know about GUIs for GDB (except the quite old DDD), but there might be one or several.<div><div></div><div><br>
